nates possible high frequency oscillations. Care should be

taken when calculating the -3dB frequency in that an incor-

rect combination of R

and C

will cause rolloff before

20kHz. A typical combination of feedback resistor and ca-

pacitor that will not produce audio band high frequency rolloff

is R

Ω and C

-3dB point of approximately 320 kHz.
